For C language users:
Step 2: Edit and save the code with vim or nano.
(code path: /home/Adeept_Sensor_Kit_for_RPi_C_Code/08_relay/relay.c)
Step 3: Compile
$ sudo gcc relay.c -o relay -lwiringPi
Step 4: Run
$ sudo ./relay
For Python users:
Step 2: Edit and save the code with vim or nano.
(code path: /home/Adeept_Sensor_Kit_for_RPi_Python_Code/08_relay.py)
